Mobile Toilet Drainage Reservation

When reserving drainage for mobile toilets, it is crucial to focus on the planning of emergency maintenance access. The specific requirements are as follows:

1. Access Width and Layout

• Single-row toilet layout: For every 5 mobile toilet units, a 1.2-meter-wide access passage must be reserved, with a length covering all toilet areas to ensure space for personnel movement and equipment operation.
• Double-row toilet layout: The access width must be ≥1.5 meters to accommodate the entry and exit of cleaning vehicles (such as sewage trucks and maintenance trucks), preventing vehicle collisions with toilet units or access facilities.

2. Access Location Selection
The access should be located on the side or rear of the toilet units, avoiding direct placement in front of the audience's line of sight or main walking routes to minimize interference with event participants. If space is limited, temporary barriers or signage should be used to guide pedestrian flow around the area.

3. Coordination with Other Facilities

• Power equipment spacing: The power supply lines for mobile toilets must maintain a minimum safety distance of 0.5 meters from the maintenance access to prevent electrical hazards and facilitate line maintenance.
• Fire safety equipment coordination: The distance between the access and fire extinguishers, fire hydrants, and other fire safety equipment must be ≥1.5 meters to ensure quick access to firefighting equipment in emergencies and prevent the access from being blocked by equipment.
• Waste transfer station connection: If a mobile toilet waste transfer point is present on-site, a separate waste removal access must be reserved to prevent cross-traffic between waste transport vehicles and maintenance access, which could cause congestion or sanitation issues.

4. Optimization Measures for Special Scenarios

• Nighttime events: Emergency lighting equipment (such as LED warning lights) must be installed in the access to ensure sufficient lighting and prevent accidents caused by poor visibility, such as personnel tripping or equipment collisions.
• Extreme weather response: During heavy rain or strong winds, a drainage slope (≥2%) must be provided along the edges of the access to prevent water accumulation and ensure smooth passage. Temporary facilities should also be reinforced to prevent them from being blown over.
• Peak pedestrian flow management: In areas with concentrated toilet use (such as near the main stage), temporary signage or staff should be used to direct pedestrian flow and prevent overcrowding in the access, which could lead to stampede risks.

By reasonably planning the width, location, and coordination of facilities for the access, the maintenance efficiency of the mobile toilet drainage system can be ensured, while also safeguarding the safety and order of the event site.
